TEMPLET.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed. October 11, 1907. Serial No. 396,977.

0 all whom it may concern:

Be it known that I, HARRY B. ASH, a subj ect of the King of Great Britain, residing at St. Louis, State .of Missouri, have invented certain new and useful Improvements in Templets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in teinplets; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a top plan of my templet as applied to an anglebar; Fig. 2 is a transverse vertical section on the line 22 of Fig. 1 Fig. 3 is a longitudinal vertical section on the line 3-3 of Fig. 1; Fig. 4 is an enlarged vertical section taken through the gage-block on the line 44 of Fig. 1, showing the centering-punch in elevation; Fig. 5 is a sectional perspective on the line 5-5 of Fig. 3; Fig. 6 is a perspective of the box or sliding member mounted on the longitudinal bar or member of the templet Fig. 7 is an end view of the templet shown secured to an Ibeam; and Fig. 8 is an end view shown clamped to a plate.

The present invention is an improvement 011 the templet constructions shown and de scribed in my pending applications Serial Numbers 368,103, and 370,999 filed respectively April 13, 1907 and April 29, 1907; and while contemplating the several objects of devices, the present improvement possesses the advantage in that it may be more quickly manipulated so that a minimum amount of time is consumed in marking the centers of holes to be drilled or punched.

A further advantage is possessed by the present construction in that special provision is made thereon for permitting a rapid positioning of the templet on the structural member (or plate)'on which the centers are to be marked, so that considerable time is saved from this feature.

The advantage of the invention will be better apparent from a detailed description thereof which is as follows:

Referring to the drawings, and for the present to Figs. 1 to 6 inclusive, 1, represents the longitudinal member or bar of a templet and may be of any length. This member has its upper surface provided with a graduated scale s, and is preferably of a cross section as represented in Fig. 2, being provided with lateral longitudinal grooves 2 to receive corresponding tongues 3 of an open .channel box or member 4 adapted to slide along the member 1, said box member being preferably of a form as shown in Fig. 6, wherein it is shown detached.

Extending laterally from the terminal heads of the box 4 are arms 5, 5, whose outer vertical faces are provided with a graduated scale 5. Along these laterally extending arms are mounted the gage-blocks 6, which may be clamped in position by clamping screws 7 engaging the upper faces of the arms, and additional screws 7 engaging the vertical faces thereof. The gage-blocks overhang the arms 5 a suitable distance, and in said overhanging portions are mounted the center-punches 8, each punch being provided with a terminal head 8 between which and the gage-blocl is interposed an expansion spring 9 coiled about the shank of the punch by which the latter is restored to its elevated position. The necessary reciprocation to which the punch is subjected with any driving blow imparted thereto by a sledge or hammer is permitted by the elongated slot 10 formed in the end wall of the block 6, a securing pin or screw 11 secured to the punch and loosely operating in said slot preventing the punch from dropping out of the block.

In Figs. 1, 2, 8, the templet is shown fastoned to one leg of an angle-bar A in which the centers of the holes to be drilled are indented by striking the heads of the punches, each punch being restored to its normal elevated position by the spring 9. In securing the templet to an angle-bar, the bottom central tongue 12 with which the member 1 is provided, is extended in the form of an arm 12 at a convenient point along the length of the member. The contiguous leg of the angle bar is then brought up squarely against the side of the tongue 12 and the adjacent face of the arm 12 (Fig. 2), and an ordinary bench clamp C with its screw 13 is made to embrace the leg of the angle-bar and arm 12, when by driving home the screw 13, the templet is secured to the structural member A. Where the structural member for example is an I-beam or a tee as shown at B in Fig. 7, a special angle-piece 14 is temporarily secured to the depending arm 12 whereupon a clamping screw 15 on the angle-piece is screwed up against the adjacent face of the flange of said member B. WVhere the structural member is a mere plate P such as a sheet of boiler iron as shown in Fig. 8, the member 1 may be held in place by a recessed block 16 embracing the member 1, the block itself being clamped to the plate by a benchclamp C such as shown in Fig. 2. The manner of clamping the templet to the particular structural member or plate operated on however, is not here claimed, but the several ways are herein illustrated to show how the templet may be utilized on different classes dented on the structural member.

of constructions.

The operation of the device is readily understood by a reference to Fig. 1. The templet being clamped in position, the gageblocks 6 (either one or both) are adjusted to the proper distance from the member 1, such distance being indicated by the scale s and then clamped to the arms 5. The boX 4 is then shifted along the member.1 the necessary number of divisions or marks on the scale sand the centering punches are struck with a mallet at the proper intervals and the centers of the holes to be drilled are thus in- The edges of the blocks 6 and of the member 4 serve as indexes or edges along which the divisions of the respective scales 8 and s are read as clearly obvious from the drawings. Of course any number of arms 5 may at any time be placed out of commission, and two gage-blocks may be mounted on a single arm; and in fact the member 4 may be provided with but one arm 5 without in any wise departing from the nature of my invention.

Such details as may be shown but not referred to are Well understood and a description thereof is unnecessary. The member 1 is preferably made of wood and may be composed of a number of sections scarfed or otherwise united together if desired, and may be of any length The extension 12 may be either integral with the tongue 12, or a separate piece may be set in the path of the tongue and secured in place as shown best in Figs. 3 and 5. These features are wholly immaterial however.

Having described my invention what I claim is- 1. A templet comprising a longitudinal member, a member shdably mounted there- 4 on, arms projecting laterally from said sliding member, gage-blocks mounted .to slide on sald arms and overhanging the same, and

centering punches mounted in the overhang-' ing portions, substantially as set forth.

2. A templet comprising a longitudinal member provided with an upper graduated scale, a member slidably mounted thereon, arms projecting laterally from said sliding member and provided with graduated scales on their vertical faces, gage-blocks mounted to slide on the arms to and from the longisuitable distances from the arms,

tudinal member, and centering punches mounted in the blocks, substantially as set forth.

3. A templet comprising a stationary longitudinal member, a member slidably mounted thereon, arms projecting laterally from said sliding member, gage-blocks mounted to slide on said arms and having portions overhanging the same, centering punches carried by the overhanging portions, and means located at the bottom of the longitudinal member for limiting its position on a structural member to which the templet is secured, substantially as set forth.

4. A templet comprising a longitudinal stationary member, a member slidingly mounted thereon, arms projecting laterally from said sliding member, gage-blocks slidably mounted on said arms, punches in the blocks, and a depending tongue disposed along bottom of the longitudinal member for engaging the abutting face of a structural member to which it may be secured, substantially as set forth.

5. A templet comprising a longitudinal stationary member, a member slidingly mounted thereon, arms projecting laterally from said sliding member, gage blocks mounted on the arms and adjustable to and from the longitudinal member, punches in the blocks, a tongue disposed along the bottom of the longitudinal member, and an eX- tension or arm dependingfrom and forming a continuation of the tongue for engaging the leg of a structural member to which the templet is to be secured, substantially as set forth.

6. A tem let having a longitudinal member, a latera l ly projecting arm adapted to be shifted along said member, a gage-blockadjustably mounted on and overhanging. the arm, and a punch carried by the gage-block, substantially as set forth.

7. A templet comprising astationary longitudinal member having a basal depending tongue for limiting its position on a structural member, a series of laterally projecting parallel arms adapted to be conjointly shifted along the longitudinal member, the latter having a scale for defining the spaces through which the arms are shifted, gageblocks slidable onthe arms to and from the longitudinal member, said arms having scales cooperating with the blocks, and centering punches mounted in the blocks at the parts operating substantially as, and for the purpose set forth.

In testimony whereof I aflix my signature, in presence of two witnesses.
